I would say Blades UK is a very trustworthy place to buy from- I can't think of a single complaint that I have even heard of from here (although I must admit I don't spend much time on the forum), and certainly have no complaints of my own. So far I have only purchased a knife, two swords, a crossbow, and strings/ bolts for the crossbow, but they have all been exactly as described or better, arrived quickly, and have been very good value for money.
Hope this helps you decide!
